Step S303, determining whether the first time difference is greater than the second time difference.
And step S304, if the first time difference is larger than the second time difference, sending out a prompt message of bad state deterioration of the pressure plate of the power distribution cabinet of the booster station.
Specifically, the change trend of the state of the pressing plate can be further mastered according to the relation between the first time difference and the second time difference, so that the pressing plate can be maintained in time.
As shown in fig. 4, as an alternative embodiment, the method further includes, after determining whether the time span of the platen during the last complete forward sliding is greater than the time span of the platen during the last complete forward sliding:
